LIQUID COOLING AND DISPENSING- APPARATUS.

Application led April 5, 1915, SeriaI No. 19,299.

To @ZZ whom t may concern.'

Be it known that we, HENRY DOERING, CHARLES Donnino, Jr., and MAX DOERING, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid Cooling and Dispensing Apparatus, of which the following is a description, reference being had to the accompanying drawings, which form a part of our speciiication.

Our invention relates to an apparatus for cooling and dispensing liquids, provided with a removable container or bottle wherein the liquid, suoli as minera-l or distilled waters, and the like, are originally placed at the source of supply, and the container or bottle adapted to be inserted into place on our improved apparatus so as to enable the liquid or water to be drawn therefrom as required.

The object of our invention is to provide a sanitary construction enabling the with* drawal of water directly from the original container or bottle without permitting the portions of the container or bottle, which come into Contact with the hands of the manipulator-s, to contact with the fluid or water, or with the portions through which the water passes; the construction being such that dirt or other extraneous matter cannot ind its way into the liquid or water.

Another object of our invention is to provide a construction wherein the original container or bottle will be provided with an automatic valve, which will permit the container or bottle to be inverted into place without permitting` any leakage of 'the liquid while the original containeror bottle is put into place, or during the displacement of one container or bottle by another before the displaced container or bottle has been completely emptied. Our improved construction is such, however, that proper placing of the original container or bottle will result in the opening of an automatic valve, and permit the liquid or water to flow from the original container or bottle into the cooling chamber until its capacity has been reached and as the liquid or water is being dispensed or withdrawn from time to'time.

Another object of our invention is to provide an apparatus of the class specified wherein the water resulting from the melting ice may drain from the cooling chamber Speccation of Letters Patent.

without, however, permitting air to enter the chamber to aitect the temperature therein.

.Another object of our invention is to provide a construction wherein the operation of the faucet for the purpose of withdrawing the liquid will automatically permit sufficient air to enter the apparatus, or rather the water-containing chamber, in order to permit a proper flow of the liquid.

Another object of our invention is to provide a second compartment into which the drip from the faucet, as well as the drain from the coolingchamber, may be received; the invention possessing other advantages inherent in the construction, which will be readily comprehended "rom the following detailed description ot the drawings wherein TFigure l is a vertical sectional view of our improved apparatus illustrating an `original container or bottle, with a portion broken awa, while the liquid-receiving chamber and its connections are shown in full lines.

In the particular exemplification of our invention, the main or body portion 15 of the apparatus, which is made of suitable material, such as sheet metal, and the like, is divided into separate compartments; the upper compartment 16 constituting the cooling chamber, while the lower compartment 17 constitutes a storage chamber.

The cooling chamber is preferably formed by providing an inner wall 18 suitably spaced apart from the outer wall of the body portion so as to provide an intermediate space to be provided with suitable material, as shown at 19, of indifferent or nonheat conducting character; the inner wall 18 vbeing extended throughout the upper chamber or compartment so as to completely insulate said chamber. The outer and inner walls of the cooling chamber are provided with registering openings to receive a covermember or lid 20, see Fig. 1, which is preferably made with a depending wall so as to contain. suitable non-heat conducting material, as indicated; the opening being of suitable size to permit the cooling chamber 16 to be charged with ice. rlhe top of the cooling chamber or compartment is provided with another opening to receive the cupshape member 21, which is provided with the depending portion 21a, adapted to extend a distance into the cooling chamber 16; the depending portion 21 being of sufficient depth to receive the neck of an inverted original container or bottle 22 so as to permit the container of bottle 22 to rest on the flared rim or saucer-shape portion of the member 21. The bottom of member 21 is provided with. a central opening adapted to receive the upwardly projecting tube or spout 23 formed on the extension 24 of the water-receiving member or vessel 25. ln order to prevent accidental displacement of member 21, we prefer to surround the opening in the lower part thereof with a shoulder or flange 26 adapted to receive the setscrew 27, whereby member 21 may be clamped to the outwardly presented tube or -spout 23.

rlhe water-,receiving chamber or member 25 is preferably provided with the brackets 28 whereby the vessel or member 25 will be held a sufficient distance above the bottom vof the cooling member, thereby not only permitting the cooling agent to completely surround the chamber or member 25, but also permitting proper drainage of cooling cha-mber 16 through the downwardly presented drain-tube 29. he drain-tube 29 extends through the lower wall of the upper commember 33 is 'made of, greater depth at the point where it receives the tube or pipe 29; while the unattached end is provided with an upwardly sloping bottom, as shown at 33a, terminating in the lip -portion 33h whereby the overflow from seal-member will be directed or discharged into vessel 34 located in the compartment 17, as shown in F ig. 1.

The inner wall 18 of the cooling chamber 16 is preferably provided with the angle member or bracket 35, see Fig. 1, which is adapted to overlap the member or bracket 36 secured to the rear of vessel or member 25 when the latter has been properly put into place, so as to prevent upward movement of vessel or member 25 when the original container or bottle is lifted off of member 21.

The forward portion of vessel or member 25 is provided with a suitable discharge tube or pipe 37 arranged to extend through a suitable opening in both walls of the cooling chamber; the tube or pipe 37 being preferably screw-threaded7 as shown in Fig. 4, so as to not only be removably secured in vessel or member 25, but also to receive the faucet 38 which is preferably screwed thereon, as shown in Fig. 4. rEhe tube or pipe 37 is preferably provided with a shoulder or flange 37 in order to effect a tight connection with the wall of the apparatus. The tube or pipe 37 has an inner wall or dia phragm 37b formed so as to provide a passage 39, see Fig. 4, which is merely open at the forward or faucet end. The outer or faucet end of the tube or pipe 37 constitutes a seat for a valve 40, which latter is provided with a stem 41 surrounded by coil spring 42, whereby the valve is normally held on its seat. rlhe outer end of stem 4l is provided with a suitable handle 43, pivota-lly secured thereto, and having its fulcrum or bearing point on the faucet 38 at the point 44, so that downward pressure on handle or lever 42 will cause the pivoted end thereof to move valve 40 from its seat. The faucet 38 is also provided with an air inlet or port 45 at a point in close proximity to the open end of passage 39, whereby air is permitted to flow through port 45 and into passage 39 when the valve 40 is removed from its seat. The inner end of passage 39 communicates with a tube or pipe 46, located within the cooling chamber, and extends preferably along the side of member or chamber 25, and connects with the upper portion of the extension 24, as shown in F ig. 1.

The tube or spout 23 extends slightly into extension 24 so that an air chamber will be formed in the upper part of extension 24 after the liquid has risen in extension 24, so as to cover the lower end of tube 23. This accumulated air will prevent the liquid or water entering tube 46; the quantity of air mames in the upper` part of extension 24 being supplied by tube 46 with each operation of the faucet.

After the container or bottle 22 has been filled at the source of supply, it isprovided.

neck or spout of container or bottle 22, as

shown in Fig. 1, so as to provide a fluidtight connection.

The stopper 47 is provided with a passage 47 C extending longitudinally therethrough, see Fig. 6, the one or outer end whereof may flare, as shown, so as to enable the spout or tube 23 to readily enter the passage 47 C.

The other or inner end of the passage 47C is provided with a valve 48, of hard rubber or other suitable material, retained or hingedly secured in place by member 49, which is pivoted to the staple 50, whose prongs or legs are suitably embedded in the plug or stopper, as shown in dotted lines in Fig. 6. Pivotaily secured on the valve 49 is a substantially U-shape member 51, see Fig. 5, the upwardly presented legs or portions whereof are each provided with coiled in dotted lines in Fig. 6.

springs 52. lThe upper ends of the springs 52 bear against the looped or encircling portions of rods or members 53, 53, suitably embedded in the plug or stopper 47, as shown rllhe looped or encircling portions of members 53 receive the upper ends of the U-shape member 51. It is apparent from the construction shown and described that springs 52 normally maintain the valve 48 on its seat, thus closing passage 47 C against the flow of liquid therethrough.

rlhe upper part of tube 23 is preferably provided with the extended converging portions or lingers 23?,232 arranged diametrically opposite each other, thereby providing sufficient space to the sides thereof. These portions or fingers 28a are preferably bowed, as shown, and provide a sliding contact with the under side of valve 48, when the container or bottle 22 is put into place. rEhe tube 23 is made to extend into member 21 a sufficient distance to enable the fingers 28- tc push valve 48 upwardly against the action of springs 52, 52, when the container or bottle 22 is seated on the ri'in of the member 21, as shown in Fig. 1.

TWith container or bottle 22 in place as described, it is evident that the liquid will be permitted to flow out of bottle 22 down through tube 23, into extension 24 and thence into receiving-chamber or member 25; a suficient quantity of air being permitted to flow into container or bottle 22 to permit proper flowtherefrom. As soon as the water or liquid has filled chamber 23 and extension 24 it ceases to iow from container or bottle 22. As faucet 38 is operated to withdraw water, air is permitted to flow into the upper part of extension 24, and thence into bottle 22 by meansof tube 23, in sufcient quantities to equalize the pressure and cause a proper iiow of the water or liquid. v

The water or liquid-entering chamber or member 25 will be cooled by the ice in chamber 16; the withdrawn water being immediately replaced by flow from container or bottle 22.

In order to protect the upper wall of chamber or member 25 from injury by the ice falling thereon, we have shown the top provided with a corrugated plate 54, which may be formed so as to fit about extension 24, and be suitably held in place.

In vertical alinement with faucet 38, and at a point beneath the bottom of cooling compartment or chamber 16, we provide the wall of the body 15 with'an opening or slot 55, see Fig. 1, about which we secure a dripcup 56, adapted to receive the drip from faucet 38 during operation thereof.

As our improved apparatus is especially adapted to the use of sanitary or collapsible paper cups, we provide the cup-portion 56 with an incline 56a, extending slightly through the slot or opening 55 in the wall of the apparatus, so as to not only direct the water dripped thereon, but also the discarded or used collapsed cups into the receptacle 34, removably set in compartment 17 of the apparatus.

As the body of our improved apparatus is shown as preferably made cylindrical, we show one wall of receptacle 84 curved to conform to the wall of the body, to permit proper placing of the receptacle, as is more clearly shown in Fig. 3. The bottom of compartment 17 may also be provided with suitable lugs or stops, as shown at 57, see Figs. 1 and 3, which insure the proper placing of receptacle 34.

The compartment or chamber 17 is of a size sufficient to receive an eXtra. container or bottle 22, to replace container or bottle 22 when the latter has become empty, at which time the empty bottle 22 may be stored in chamber 17, out of the way. The rear wall of the main body 15 is provided with an opening, as shown in Fig. 2, sufficiently large to permit the bottle 22a to be readily passed therethrough, as well as vessel or receptacle 34. The opening is preferably closed by the sliding door 56 which is bowed to conform to thecurvature of the wall of body 15, and slides along the inside of the wall or body 15, being held in proper sliding position by the rail 59, secured at the top, and rail 60, secured at the bottom of chamber 17, as shown in Figs. 1 and 3.

In order to permit access to the upper or cooling chamber 16 for the installation of the water-receiving member or chamber 25 and its parts, we construct the body 15 with a removable top 61 provided with insulating material and adapted to fit into the upper part of body 15 onto a shoulder 62, preferably formed on the inner wall 18 of the cooling chamber or compartment 16, see Fig. 1.

The body 15 may be provided with any suitable support, as, for example, legs 63 of suficient number, which may be riveted or otherwise secured inplace. v

We have also shown the apparatus provided with a sanitary cupholding and dispensing device 64, see liig. 1; the device being arranged to feed the cups, one at a time, upon proper manipulation of the flange or slide-member 65. As this device forms the subject-matter of a separate application, a further detailed ldescription thereof will not be entered into.

It is apparent from the foregoing description of our invention that drinking water or liquid may be dispensed from the original containers or bottles, which are closed by the Stoppers 47, as soon as the bottles have been charged, thus obviating the possibility of any foreign matter, dirt or bacteria getting into the water, as the outer wall or neck of the container or bottle cannot come into contact with the water or with the water-receiving portions of the apparatus, as is clearly apparent.

It is further evident from the construction that the container or bottle may be put into place on the apparatus or displaced while still filled with water, without in any way spilling the water, as the valve 48 will immediately become seated when the container or bottle 22 is lifted, thereby withdrawing tube 23 from the stopper 47.

The apparatus is so constructed that ready access may be had to any part thereof; and when desired the water-receiving chamber 25 may be flushed out by means of the standpipe or tube 23, before the container or bottle 22 has been put into place; a suitable hose or pipe being placed over the upper end of tube 23 and faucet 38 held open so as to allow the fiushing water to flow out of the chamber or member 25.

We have shown and described what we believe to be the simplest and best form of our invention, but the same may be modified in certain respects without, however, departing from the spirit of our invention, and we do not wish to be understood, therefore, as limiting ourselves to the exact construction shown and described.
